I don't have much experience in trading and I'm outdated using Binance exchange but here's what I say. Move your balance out quickly and find other exchanges that you didn't annoy.
I shorted the market , and Eth crashed and instead of my short paying me out +80% Binance paid me out -90%
I saw a lot of complaints regarding this but I think this is just because they included/charges more fees.
BTW, have you read the terms before using Binance?
Each exchange platforms have different strategies for how to gain profit and it might this token pump and dump will Binance gain more profit. So, you need to understand first how their trading mechanism works including the fees to which way you can save on it, I've heard using their BNB coin will traders can have lesser fees than using other cryptos.
This is the most problem f any micro traders, use their coin if you wanted to save fees or else, just a quick tip, stop using them if you aren't comfortable using them.
